[E30 Beast]

[E30 Beast]

not getting any power to the injectors, and reverse polarity on main relay, nd fuel pump relay any thoughts?

[E30 Beast]

anyone?

Did you get the Rev B of my Writeup? The electrical section was beefed up substantially.

Also, did you get the email I sent you. I had some corrections to your pin assignments.

Let me know if it helped. I didn't get any feedback from you.

Thanks,

Not to double post, but now I see what E32 plug you went with; The 25 pin C101.

This makes it much more difficult, but if you tell us which year 735i you got your E32 harness from, we can help match it up for you pin for pin.

Thanks Frank i believe the harness is from an 88 or 89 735 il, Is it possible that my motor wont start because i didn't do the TDC right?

88/89 had a 20 pin, your must might be from 90/91.... Did you look at my thread with 25pin c101 pinouts? They are all there, you just need to match them with your 20pin.

I had looked at your thread and tried to match the pins but it still wasn't getting any power to the main relays nd the fuel pump relay.

Post here what you have connected and where.

You have harness ground and power connected right?

hey guys had a question can i use any other radiators because i really cant find any out here in cali in good condition so i purchased a new one nd turns out the new one was bad could i use like an e34 or e36 radiator?

[Jean]

no, unless you modify your firewall and push the engine further back (and use custom mounts and possibly driveshaft)

[E30 Beast]

well i did already modify my firewall to position the motor as far as it could go (Good nd Tight mounts) which gives me about three - four finger clearance from the motor nd the frame would that help

[Jean]

Only one way to to find out, test fit one.
